The latest release of Microsoft OneDrive brings some great functionality of accessing your files and folders On-Demand. Enabling this can save you tons of space on your hard drive, and, if you use with Selective Sync, you have an even better way to manage everything!
I highly recommend getting an Office 365 Family subscription. Not only can you use the online version of the various Office apps, you can also download and install the Office software on 6 devices (Mac or PC). The annual subscription is around $99.
